OLIVER CHARLES DORNEY, OF ALLENTOWN, PENNSYLVANIA.

SPECIFICATION forming .part of Letters Patent-No. 722,003, dated March3, 1903. I

Application filed $eptember'L1901. Serial No. 74,666. (No model.)

To aZZ whom it may concern:

Be it known that I, OLIVER CHARLES Don- NEY, a citizen of the UnitedStates, and a resident of Allentown, in the county of Lehigh and Stateof Pennsylvania, have invented a new and Improved Table, of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in tables particularly adaptedfor use by artists, architects, and the like; and the object is toprovide a table that may be readily adjusted as to height and angle andhaving supporting devices for lamps and tools or instruments, such asbrushes, drawing instruments, colors, inks, &c.

Further objects will appear in the general description. "I

I will describe a table embodying my invention and then point out thenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is an elevation of a table embodying'my invention and showingthe several attachments thereof. Fig. 2 is a side elevation of thetable. Fig. 3 is a sectional detail showing a means for raising andlowering the table. Fig. 4 is a section on the line 4 4 of Fig. 3. Fig.5 is a sectional detail showing a means for supporting and adjusting atool-holding stand. Fig. 6 is a section on the line 6 6 of Fig. 5. Fig.7 is a section showing a center pivot for the table-top. Fig. Sisasection on the line 8 8 of Fig. 9. Fig. 9 is a section on the line 9 9of Fig. 8. Fig. 10 is a section on the line 10 10 of Fig. 8. Fig. 11 isa section on the line 11 11 of Fig. 8. Fig. 12 isia section on the line1212 of Fig. 8. Fig. 13 is a section on the line 13 13 of Fig. 14. Fig.14 is a section on the line 14 14 of'Fig. 13, and Fig. 15 is a sectionaldetail showing a clamping-screw employed.

As here shown, the table-top comprises three sections 20, 21, and 22.The outer section 20 is made square or has parallel straight edges, withwhich the head of a T-square may engage. This section 20 is providedwith a central opening, in which the circular section 21 is designed to'rotate, and this section 21 is provided with an angular orsquareopengether by means of fastening-bolts 23.

ing, within which the square section 22 is removably placed. By thisconstruction the sections 21 22 may be readily rotated with relation tothe outer section to bring the work to proper position and the section22 may be readily removed and turned or a new one with another drawingmay be put in its place. The several sections are each made of strips ofmaterial glued together at the edges. The sections 20 and 21 have theirstrips mitered together at the ends, and these ends are not only glued,but they are further secured to- As clearly indicated in Fig. 12, thefasteningbolts are passed through openings arranged at right angles tothe mitered ends, and the ends of the bolts are projected into recesses24, formed in the strips, so that the fastening-nuts 25 may be placedthereon and-tightened. These-recesses will be formed in the bottom ofthe table-top, and after tightening the bolts the recesses may be closedby means of plugs 26.

The center section 22 is supported on plates 27, secured, by means ofscrews or otherwise,

to the under side of the section 21, and this section 21 is supported oninwardly-extended lugs 28 on a metal ring 29, attached to the under sideof the outer section 20. While the sections 21 22 may be rotatedrelatively to the section 20, and for the convenience thereof I haveprovided the section 21 with knobs 30, the several sections are designedto rotate together and also to have a tilting movement to adjust theangle of the tabletop, and the table-top is also designed to have avertical adjustment with relation to the base or leg portion 31. I

Supported by the base or leg3l are the standards 32, which arescrew-threaded for a portion of their length. These standards 32 engagewith the interior thread of nuts or sleeves 33, arranged in boxings 34on the base, and to reduze friction to a minimum I arrangeantifriction-balls 35 between the lower ends of the nuts or sleeves 33and the bottoms of the boxings 34.

It will be seen in Figs. 3 and 4 that the lower end of the nut or sleeveis provided with a raceway, as is also the upper surface of the bottomof the boxing. To prevent a rotary movement of the standards 32, I pro-Vide the same with longitudinal channels 36, into which lugs 37 on thebottom portions of the boxings extend. The inner walls of these channels36 may be spaced off in inches and properly numbered, so that the tablemay be adjusted accurately to the height required, the numbers of thescale showing over the upper ends of the boxings 34. The opposite nutsor sleeves 33 are provided at one end, as here shown the lower end, withbevel-teeth 38, which are engaged by bevelgears 39, the two oppositebevel-gears being connected to the ends of a shaft 40, which is in theform of a crank-shaft, having a handle 41 at its center. Obviously byrotating the crank-shaft 40 the standards 32 may be simultaneouslyraised or lowered.

Mounted to swing on each standard 32 is a segmental rack 42, thesesegmental racks passing through openings 43, formed in the standards.The upper or connecting bars 44 of the racks are pivoted at theircenters to the upper ends of the standards, as clearly indicated in Fig.2. The ends of the opposite racks 42 are connected by cross-bars 45, ashere shown, by means of set-bolts 46. The ends of these cross-bars 45have bracket portions 47, in which bearing-rollers 48 are mounted, thesebearingrollers being designed to engage with the ring 29.

As shown in Fig. 11, the rollers 48 may be provided with annularchannels to receive the rubber rings 49. The opposite cross-bars 45 areconnected at the center by a center bar 50, which has at its center acup or step bearing 51 for a spindle 52, which extends upward through anopening in a bar 53, connected at its ends to the ring 29, and the upperend of the spindle is engaged,bymeans of a screw 54, with a cup orcasting 55, secured in a recess formed in the under side of the table-top section This spindle serves more as a centering device for thetable-top,

as the main bearing of the table-top is on they rollers 48. When it isdesired to remove the section 22 of the table-top, the spindle willberemoved with it.

The centering-racks 42 are secured in their adjusted position by meansof a locking-bar 56, which is mounted to move longitudinally in openings57, formed in the standards, and these locking-bars are mounted on links58, arranged in said openings, the lower ends of the links beingattachedto pivots on the standards, while the upperends are pivoted to thelocking-bar. The ends of this locking-bar project outward beyond theouter sides of the standards, so they maybe readily grasped at eitherend for the purpose of moving the bar. Obviously by drawing thelocking-bar outward the links 58 will cause it to lower and release itfrom the notches in the racks, so that the table-top may be readilyswung to adjust its angle. After such adjustment the locking-bar is tobe moved to its normal position to engage in a notch in each rack. Thebar is prevented from moving too far outward by means of pins 59 on saidbar and adapted to engage against the inner sides of the standards.

Supported on each standard is a bracket for holding a lamp or the like.These brackets are designed to swing transversely and also to have avertical movement. As here shown, each bracket consists of a pivot-block60, mounted to swing in a horizontal direction on pins 61, extendedoutward from the upper portion of the standard, and connected to thisblock 60, so as to swing up and down with relation thereto, are parallellinks 62, which at the other end have pivotal connection with an arm 63,and mounted to swing in a horizontal direction on this arm 63 is anotherarm 64, to which a shelf 65 is attached. By this construction it will beseen that the block may swing horizontally with relation to the section63, and therefore the shelf may be placed in any convenient positionover the table-top or at one side thereof. The links 62 may be held asadjusted by means of a set-screw 62, which forms the pintle for thelower end of a link. Also mounted to swing and adjustable vertically ofthe standards are cabinets 66, which may be made in any desired form. Ihave here shown the cabinets as provided each with a set of drawers forholding brushes or other instruments. Each cabinet has a pivotalconnection 67 with the end of an arm-section 68, having horizontalswinging connection with an arm-section 69, having aninteriorly-threaded portion 70, which engages the thread of thestandard.

By referring to Fig. 5 it will be seen that the pintle connectionbetween the arm-sections 68 and 69 consists of a tubular pintle 71,having a head portion 72 for engaging loosely on the top of thearm-section 69. Supported by each pintle is a shelf 73, upon which aplaster cast,model, or other device may be placed. The shelf has ascrew-threaded stem 74, engaging with a nut 75, which removably engageswith the top of the head 72 of the pintle, but is prevented from rotarymovement with relation thereto,as here shown, by means of a rib 76,engaging in a groove 77 in the upper surface of the head 72. Obviouslythis arrangement may be reversed--that is, the rib placed on the head 72and the nut provided with the channel.

When it is desired to raise or lower the shelf 73, it is only necessaryto rotate it so that its stem 74 will move through the nut 75. Thecabinet 66 may rotate relatively to the arm-section 68, and thearm-section 68 may swing on the pintle 71 relatively to the armsection69, and by lifting the shelf 73, with its stem and nut, out of thetubular pintle the pintle may be removed, so as to separate thearm-sections 68 and 69, and then the armsection 69 may be rotated on thethreaded standard to raise or lower it, as desired. The base portion ofthe table may be provided with shelves 78 and 79, under which drawers 80and 81 are placed.

It is obvious that a table embodying my invention will be found veryconvenientfor the use of artists or students, as it may be readilyadjusted to desired positions or angles by aperson withoutleaving hisseat. By making the table-top of the strips secured together, as shownand described, it will not be subject to warping, and when the severalsections of the top are together the top surfaces will all be on oneplane.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a table, a base, standards adjustablevertically with relation to the base, means for causing saidadjustments,racks having swinging connection with the standards, alockingbar movable through openings in the opposite standards andadapted to engage with the racks, swinging links supporting saidlocking-bar, and a table-top supported on the racks, substantially asspecified.
